Chemotypic Variation in Indian Lantana camara Essential Oil

Abstract

The essential oil from the leaves of Lantana camara from Dibrugarh, in the northeastern Indian state of Assam, after spectroscopic analysis, has shown that cis-davanone, an uncommon sesquiterpenoid, is its major constituent, while the essential oil from flowers contained β-caryophyllene and bicyclo-germacrene as the major components. Presence of davanone in the essential oil from leaves of this region clearly showed that L. camara exists in the form of another chemotype in the northeastern part of India as compared to north and north central India, wherein β-caryophyllene is the major component. The oil has been extracted from three different locations of the northeastern region successively for four years to confirm the stability of the chemotype
